Condell Park Water Hardness & Quality Report (2026)

Condell Park's drinking water is supplied by Sydney Water, treated at the Prospect Water Filtration Plant with an elevated Hawkesbury-Nepean component for the Canterbury-Bankstown City LGA inner western distribution in New South Wales. Water hardness in Condell Park is measured at 166 mg/L — classified as moderately hard — within the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Condell Park — a residential suburb in the inner western Canterbury-Bankstown LGA adjacent to Bankstown and Bass Hill, known for the Condell Park industrial and commercial estates on Mimosa Road, the Canterbury Road residential community, and the diverse multicultural residential character of the inner western Canterbury-Bankstown corridor — receives moderately hard supply consistent with the harder northern Canterbury-Bankstown distribution zone driven by elevated Hawkesbury-Nepean blending.

Condell Park's elevated hardness reflects a dominant Hawkesbury-Nepean component in the inner western Canterbury-Bankstown Prospect distribution blend. The Hawkesbury-Nepean system traverses the Cumberland Plain alluvial valley and Triassic carbonate-cemented Hawkesbury Sandstone — contributing high dissolved calcium and minerals before Prospect treatment — particularly affecting the inner western Canterbury-Bankstown distribution routing. The Condell Park inner western distribution at 166 mg/L and TDS 373.3 mg/L is consistent with the harder northern Canterbury-Bankstown sub-zones (Yagoona 168 mg/L, Chester Hill 148 mg/L), in sharp contrast to the soft southern Canterbury-Bankstown sub-zones (Riverwood 52.5 mg/L, Padstow 52.5 mg/L).

Condell Park residents face moderate-to-significant limescale build-up on taps and in kettles — descaling every four to six weeks is typical. Hot water systems benefit from regular inspection. The elevated lead reading (0.004 mg/L) warrants briefly running the cold tap before use. Sydney Water provides water quality information at sydneywater.com.au, with all ADWG health standards consistently met. Condell Park's Canterbury-Bankstown inner western residential community benefits from supply meeting all ADWG safe drinking standards.
